Nobiles Officinae

The Royal Workshops in Palermo during the Reigns of the Norman and Hohenstaufen Kings of Sicily in the 12th and 13th century

In the Nobiles Officinae, Moslems and both Greek-Orthodox and Roman-Catholic Christians, who were probably all classed as "local artists", were employed side by side.

Among the world-famous as well as historically and artistically uniquely valuable treasures now housed in the Secular Treasury, the regalia of the Holy Roman Empire are surely the most outstanding and important. However, the most important pieces making up the coronation robes were not made anywhere within the territory of the Holy Roman Empire, and they were not originally intended for the ruler of the Empire.
